This is the first avatar from mine and Boxwolf's store, Luminotic.

The kaokao is a rodent like creature that can gradually emulate other beings' actions and speech. Initially, they can only make clicks or squeaks. They are often in groups of 3-5, but they can be solitary or may travel in mass communities on occasion.

The avatars of all available colors (not including limited editions and seasonal) are available from the mainstore here.
